Nope, he said "Bye" and I reciprocated, nothing more.
If he wants to take his ball and go home because those in the know don't agree with the 20lb tag, then so be it.
It would seem that most said "nice fish" even if they disputed the 20lb claim and it is indeed a nice fish. Easy to get caught up in the excitement and over estimate it's size when it's your best ever, but as I said, those in the know, know.
No need to get upset if it's not a 20lb, it's still a solid fish and a benchmark for future efforts.
And for the record the lack of an obvious fin clip does not guarantee that it's a wild fish.
